Metal Spacer Sleeves play a vital role in ensuring accurate spacing, alignment, and load distribution in mechanical assemblies. At Ningbo Yihu Hardware Manufacturing Co., Ltd., we provide tailored fastening solutions, specializing in high‑precision Metal Spacer Sleeves manufactured by advanced cold forming technology.
Serving the Automotive, Industrial, and Energy industries, we focus on customized components that meet strict performance, quality, and cost requirements.
Designed for automotive and high-end machinery, this precision bushing combines high-strength alloy steel with specialized Zinc-Nickel plating for superior corrosion and heat resistance. It meets strict ±0.05mm tolerances and complies with EU ELV and OEM standards (including Bosch), making it the ideal solution for critical assemblies.
Are you looking for a high-precision cold forging supplier? We specialize in multi-station cold forging and provide ±0.1mm precision fasteners, bushings, pins and complex shaped components for automotive and electronics industries.
Multi-station cold forging products are mainly suitable for automotive parts purchasers, mechanical engineers, and overseas customers such as distributors or end manufacturers in Europe and the United States.
As the automotive industry continues to demand lighter, stronger, and more precise components, traditional cutting and machining methods can no longer meet the requirements of efficient and cost-effective production. Cold heading, as a highly efficient, energy-saving, and precise metal forming process, is gradually becoming the mainstream technology in the manufacturing of automotive hardware components.
Ningbo Yihu Hardware Manufacturing Co., Ltd. has been dedicated for many years to the research and production of multi-station cold-headed parts, providing global customers with high-performance automotive fasteners and precision metal component solutions.
Cold forming or cold forging process, it ensures excellent material utilization, consistent quality, and improved part durability, making it ideal for automotive and industrial applications.
